O her important object isto provide 'a self- I contained knot tying implement that is provided with motonmeans for operating the able type. Preferably I provide means permitting the functioningof the motor by thread pressure. Other important; objects of the invention willbe-set forth hereinafter.

The structure of the implement and the form andrelation of parts 'thereof may be widelyvaried. Within. the scope and purpose :of my invention. Preferably l provide a' casing or inclosure therefor herein repre same, said motor means being of any suit- I portions of the casing. In operation, the implement is preferably supported in a convenient position on the operators body at the waist or chest, as by placing the supporting hook 4i overan appropriate belt to be worn on the body or about the neck.

'Any suitable knot tying member may be provided, and the character thereof may be varied according tothecharacter of knot that is to betied, which, for example, may be a roundyor spinners knot, or any other suitable character of knot. 'Thejmovement imparted to the knot tying member may be one of-rotation, or of any other suitable character, and my inventionyis thereforenot limited in this respect. 7 I s'h'all proceed to describe the illustrated embodiment only of the invention.

The illustrated implement is provided with knot tying bill and end severing means herein represented at 5 in Figs. 1, 5 and 8, and which may be of any well known type requiring rotation to perform the function of tying a knot. I have hereinrepresented the said tying bill as composed of two jaws 'constructed and arranged for relative movement and having provisions for shearing the threads or other strands. Inasmuch as these'parts' are of any suitable construction, a detailed description thereof is unnecessary. T he knot tying bill is mounted for rotation in a sleeve itself fixedlymounted within the member 2' of the casing. The said bill projects at its forward end through said sleeve into position to receive the threads. The casing is provided with or receives suitable motor means which may be of any desider or approved type, it being such that represented the shaft 7 thereof, one end of which is mounted in the member 1 of the casing, as having fast thereon a pinion 8 meshing with a gear 9, the teeth whereof are, in the disclosed; embodiment of the invention' cut on the oeriiherv of a motor sorin a i l u L a case 9. The said spring case has a sleeve like. portion 10 loosely mounted within a sleeve 11 herein shown as integral with the portion 2 of the casing. Mounted within the sleeve 10 is the spindle 12 of a ratchet 13, and between said ratchet and the annular flange 14c of the spring case 9 is positioned a coiled spring 15, the ends whereof are respectively secured to said spring case and to the ratchet spindle, as indicated at 16, 17. The sleeve 10 of the spring case extends forwardly'through the wall 2 of the casing, and the spindle of the ratchet extends through said sleeve 10 and is there provided with a knurled handle or knob 18 fast thereon and by. which said spring may be placed under suitable tension. I have herein represented a collar 19 fast on the sleeve 10 between the knurled handle and the wall of the member 2 of the casing. Any suitable means may be provided to wind the spring, and if desired I may for that purpose, as shown in Figs. 10 and 11, provide a strap or other flexible member 19 which the operator may pull from time to time sufficiently to keep the coil spring substantially wound up. vFor this purpose 1 preferably provide a ratchet 19 fast upon the outer end of the spindle 12. Loosely mounted upon and surrounding the spindle 12 is a drum 19 having a pawl 19 engaging the ratchet 19, said drum being provided with a spring 19 tending normally to return the drum against the winding operation. The said drum is preferably provided with flanges 19 between which is wound the strap 19, herein shown as having secured to its end a ball l9 permitting ready grasping by the operator.

Any suitable means may be provided to permit the spring to unwind but preventing the ratchet spindle 12 from turning backward during the winding operation. For this purpose I preferably provide a holding pawl 20 mounted for sliding movement in a socket 21 of the member 1 of the casing and having a head or member adapted to engage the teeth of the ratchet and held yieldingly in such relation by a compression spring 23. The spindle 2 1 of the sliding pawl is at its lower end loosely mounted in the collar 25 tapped into the member 1 of the casing and is provided with a finger piece 26 at the exterior of said member 1 in convenient position to be grasped by the operator, thus permitting said pawl to be withdrawn from the teeth of the ratchet 13. Any suitable escapement means may be provided for the spring motor. In the disclosed form of the invention, fast upon the shaft 7 of the knotter bill is a gear wheel 27 meshing with a pinion 28 fast upon an eseapement shaft 29, and whereby the latter is rotated. Said escapement shaft is mounted in suitable bearings 30, 31 in the casing members 1, 2, and has fast thereon an escapement wheel 32, the relative size of the gear 27 and pinion 28 being preferably such that the escapement shaft and its wheel 32 are rotated a number of revolutions, while the knotter shaft and the attached knot tying bill are making a single revolution or rotation.

Th escapement wheel 32 is held from turning in any suitable manner. In order to hold the knotter and the eseapement wheel from rotation, 1 preferably provide an escapement lever 33 (Fig. 7) having a pivotal stud 34c projecting through the case and having two arms 35, 36, the former of which extends upwardly viewing Fig. 7 and is adapted to engage a notch or shoulder 37 upon the escapement wheel, and the other of which extends inwardly so as to engage any one of a series of notches 38 upon the periphery of the flange 14 of the spring case 9.

I have thus far described a tying bill and motor means for rotating the same in an intermittent manner, and in the disclosed embodiment of my invention 1 have represented spring motor means and eseapeinent means therefor permitting the intermittent actuation of the tying bill through said motor means. I contemplate the provision of means broadly for effecting the release or knot.

actuation of the motor means through or by the positioning of the/threads or strands'by the ooerator. Obviously such means be i a V of widely varying form and construction, to i thedisclosed embodiment of which my invention is'in no wise limitedj p 7 p H Herein for that purpose I have represented releasingjtrigg'er (Figs. 4 and 8), which is here shown as pivot-ally mounted a't 40 upon the ease; The' saiol trigger is preterably sheathed between two walls or portions of the ease', in dicatedat ll, e2 positioned in 'close prox mity and 1n parallel sm w th sand trigger, and each having a narrow slot 43 leading down to the upper edge of the trigger and of substantially only suiiicient width to permit the insertion of the threads or other strands tofbe tied; The construction vide anysuitable means, and l have her in iorthat purpose represented the protruding end of the stud 34 ofthe escapeinent lever 33 as provided with a bent pin le, WlllCll is enegaged and liftedby' an outwardly bent end ,1 ofthesaid"trigger 39 (see i).

I provide anyisuitable thread holding and stripping ni'eansj Herein for that purpose I have represented a combined-thread holder I and stripper 46 I (Fig, 2) fast upon an upright stud i? located'in SLUEQiJlGbGZLIIIlgS 48, 49 upon 'the'exterior off the member 2 of the frame.

The said thread holder and stripper is pr vided with a terminal hook-like-memoer 50, and'inelosing the'same'is a suitable sheath or holder-51 having a depending pin or projection 52 engaging a cam slot 53 in a suitable bi eket ode' secured tothe member 2 or the casing by screw The cam groove 53 is o'tsuitablc shape to impart the proper l I movement to the thread holderand stripper.

The stud i7 e'rtendsthrough the wall of the casing 2,a'nd at its lower inner end has fast thereon aido'g56adapted to be engaged by any one of a series of pins or stnds'57, shown as threaded into the wall'ofthe spring case9. ihe said pins'ol areso relatively positioned as to engage the dog- 56 at-the 'proper times,

tying bill to rotate.

In operation, the implement is preferably supported as described "upon the body or about the neck'e'f the operator, the spring 15 being put undertension by turning theknob v 18,01 in any other suitable manner. A pair of threads toxbe united is gathered in one hand, laid across the stripper hook50, the trigger 39 andin line with the knot tymg bill 5,-the. threads being guidedinto the hook 50 of the stripper by the 1nc11ned' guide flange 2 on the casing. -A depression of the trigger releases the eseapement wheel by withdrawing the "'escapement lever from the notches 3? lnthe diselosedembodiment of the invention, by the time the escapement wheel 82 has made one revolu-i tion, the spring case 9 has moved enough "so that the arm 36 of the eseapeinent lever 22 is out engagement with the just active notch 38 of the spring carrying gear 9.

Consequently the said arm 36 of the lever 33 cannot again engagethe escapement wheel until the next succeeding notch 38 registers with the end of the arm 36 of the lever 33,

vand38, thus allowing the knot 9'0 and in this embodiment of the invention tl is does not occur untih-tlie knot tying bill has made'tw'o complete revolutions and all the other parts haveiunctioned in the tyingoi? the knot and stripping -it from the knot tying bill.

in: the appropriate time during" the said two revolutions of the knot tying bill, one of I the pins 57 engagesthestripper dog 56, cansing the stripper'arn to commence its movement to the dotted line position shownin and at the same time the cam slot 33 closes the threadholder 51 on the yarns'or' threads beino 'tied. The further swinging movement of the striyper-eo, 5Q draws'the "complete knot over the 'nose of the'knot tying bill.

After th active pine? hasvpassed the tipper dog 56,-the stripper is returned to foiled spring 58 herein shown as encircling he stud 47 am. having ts ends respectively oif thecas ng member '2 and operated by pressure of the threads theme to'oe knotted, but obviously within the broad scope o'ijmy invention, I may employ any suitable means, 01 erated by thread pressure,

While to this end, I may provide any suitable means, I have in Fig. 12 and 13 represented the pivotal stud 3 1 as having the bent pin 4L4 laterally ex- It will be evident from the fore 'oin description that when the releasing trigger 39 is depressed, the inner end thereof is elevated, thereby moving the latch 39 upwardly against and lifting the bent pin in, and thereby turning the pivotal stud 34;. In such movement of the latch 39 it contacts with the pin 39, and the atter acts to force the latch to the left, viewing Fig. 13, until the upper end of said latch rides from under the bent pin A l, thus permitting the pivotal stud 3st to return to its former position. This prevents all possibility of the spring motor running down at a single movement of the trigger.

It will be evident from the foregoing that y applying thread pressure to the trigger the motor is permitted to function. The severance of the threads with the resulting withdrawal of thread pressure from the trigger permits return movement of the trigger and therefore the thread severing action causes the automatic stopping of the motor after the functioning thereof; that is, it causes the motor to cease functioning.

So far as 1 am aware, I am the first to operate or release a self-contained motor means of-any description by the yarns or threads to be united, and 1 therefore claim the same broadly.
